The bolt, this invention, includes a container body IU havwhen extended, moves downward and is engageing a hingedly mounted cover II, a master latch able in a keeper 3l This keeper extends through I21with a resiliently extended bolt I3 mounted the` compartment of the body I0 and is mounted 55 ative position.

upon a bar 32 which is hingedly mounted at the top end 33. The bar 32 is adapted to latch the container on a Wall.

Numeral 35 indicates a Wall having a recess 36 across which a support bar 31 is mounted. The arrangement is such that the bar 32 may be engaged behind the support bar 31 and then latched in position. The dot and dash lines 38 indicate a bottle of milk Within the basket I1. The container is particularly adapted for milk, though other merchandise may of course be placed within it.

The resilient member I8 is xedly mounted at one end 39, and at the other end has an eye member 4U which extends to the exterior. A lock 4I normally engages the eye member 40 to prevent depression thereof. Y e n n The operation of the device is as follows:- When the basket I1 is empty, the springs 30 and I5a will maintain it in a raised position. AIn the raised position the latch 29 is open so that the container may be removed from and placed upon the bar 31, at will. Furthermore, inthe raised position of the basket I1 the bolt IS`is extended and prevents the bolt I3 from assuming an oper- Thus, the cover II may be closed and opened any number of times without thebolt I3 engaging beneath the keeper I4. When the cover II is closed the bolt I3, which has a cam surface at its front end, will be forced inward and maintain a retracted position against the side of the bolt I6. Y

When the objects are placed Within the basket I1 the VWeightof these objects will move the bolt 28` into operative position to latch the container uponY the support bar 31. It now is fixed and cannot be removed. The bolt I6 will be retracted so that when the cover I I is closed the bolt I3 engages beneath the keeper I4. 'Ihe device is now locked. To open the device it is necessary that the lock Y4I be removed with Ya key. Then the eye member 40 may be pressed inward to flex the resilientmember I8 so that it engages the end of the bolt I3 and pushes the bolt into its retracted position. The cover I I may then be opened.

While We have illustrated and described the preferred embodiment of our invention, it is to be understood that We do not limit ourselves to the precise construction herein disclosed and the right is reserved to all changes and modifications coming Within the scope of the invention as defined in the appended claims. i e Y Having thus described our invention, what we claim as new, anddesire to secure by VUnited States Letters Patent ist- Y 1.
